LEATHER PACKING.

To all whom it may concern:

Be it known that I, HARRY TALENT, subject of the King of Great Britain and he land, and resident of Prestwich, near Manchester, in the county of Lancaster, England, leather manufacturer, have invented a cer- Packing, of which the following is a specification.

My invention relates to engine packings or more particularly to such as are employed for packing the piston or plunger rods, rams or the like in hydraulic pumps or machinery or for other services where the construction of packing hereinafter described may be advantageous, the object being to provide a cheap form of packing from leather in such a manner as to resist wear for a considerable length of time while being pliable enough to bend into the required curves or circles around the rods or other parts and at the same time be capable of ready expansion under the pressure of a gland, ring or the like to make a tight and serviceable'joint.

My invention consists essentially in a packing formed of a number of narrow tion so arranged that one or more of the thick edges may be alternate with one or more of the thin edges at the sides of the packing, the whole being inclosed or held together by plaited or braided yarn or by other simple means.

The invention will be fully described with reference to the accompanying drawings in which- Figure l is a side elevation of a packing constructed in accordance with my invention, Fig. 2 transverse section of same and Fig. 3 transverse section showing a modified arrangement.

In accordance with my invention the improved packing is made from a number of strips of leather a of' any suitable length and width, such strips being beveled by skiving or other suitable means so as to give a wedge-shaped cross section. One edge remains the original thickness while the other is reduced to a minimum or feather edge, though it may not be reduced quite so far.

shaped section which enables the strips to be placed upon one another to any required number with some of their thick edges alternating with some of the thin edges of the other strips, in regular single order as in Fig. 2 or two thick edges to two thin ones as in Fig. 3 or in any other suitable and effective disposition, the arrangement enabling the strips to slide one upon the other laterally under the pressure of a gland or ring when in a stufiing box or groove and so accommodate themselves to the making of a tight joint. They may, however, be so placed in a stuffing box or the like as to take compression in the direction of their edges and so make a tight joint.

The strips a are relatively thin in propor tion to their width, the thick end of each wedge being about one-quarter the width of the strip, so that four pairs of strips placed together as shown in Figs. 2 and 3 will make a packing which is substantially square in cross-section.

The leather strips are usually of a soft character and are rendered still further pliable and waterproof by treating with tallow or like material though they may be used in dry form. They are held together by a covering or tube of braided or plaited yarn 6, though they may be secured by other suitable and simple means such as by sewing or by staples of wire passed through them at intervals.

The arrangement provides an exceedingly simple and serviceable packing.

What I claim as my invention and desire to secure by Letters Patent is A rectangular packing formed of strips of solid leather arranged in pairs, each strip being triangular in cross-section and being relatively thin in proportion to its width, and means for retaining the strips in position and permitting them to slide on each other to a limited extent.

In testimony whereof I have hereunto set my hand in the presence of two witnesses.

HARRY TALENT.
